DETAILED DESCRIPTION

[0018] The present application will be further described below in combination with the drawings and specific embodiments:

[0019] The specific embodiments, for example, Figures 1-3As shown in the utility model provides a kind of novel sandwich thermal insulation composite wall structure, including outer veneer 1, outer concrete layer 2, inner concrete layer 3 and the thermal insulation layer 4 between outer concrete layer 2, inner concrete layer 3, the connecting piece 5 is additionally provided between outer concrete layer 2 and outer veneer 1, the fixed part 501 of connecting piece 5 is embedded in outer concrete layer 2, the plug-in part 502 of connecting piece 5 is exposed to the outside of outer concrete layer 2, the inside of outer veneer 1 is provided with the plug-in slot 6 matched with the plug-in part 502 of connecting piece 5 along horizontal direction, and outer veneer 1 is connected with outer concrete layer 2 by plug-in connection with the aid of connecting piece 5.

[0020] The current outer veneer panel is directly adhered to the outer surface of the sandwich thermal insulation board by using adhesive, but since the sandwich thermal insulation board is prefabricated in the factory, the outer concrete layer 2 is poured in a lying type during preparation, so that the diffusivity and flow of the concrete are good, resulting in that the outer surface of the sandwich thermal insulation board is relatively smooth. Therefore, before bonding the outer veneer panel, the outer concrete layer 2 needs to be polished to make the surface rough, so as to improve the bonding firmness between the outer veneer panel and the outer concrete layer 2. However, this method increases the process of on-site construction, affecting the construction efficiency.

[0021] In order to solve the above problems, the utility model adopts the form of combination of connecting piece 5 and bonding to fix the outer veneer panel to the surface of the outer concrete layer 2. When building, first, the outer veneer panel is matched with the sandwich thermal insulation board by plug-in, then the two are rotated by 90°, so that the plug-in slot 6 of the outer veneer panel is along the vertical direction, at this time, the gap between the outer veneer panel and the outer concrete layer 2 is filled with adhesive such as mortar, adhesive and the like, the combination of connecting piece 5 and bonding not only does not need to polish the outer concrete layer 2, reduces the process of on-site construction, significantly improves the construction efficiency, and even if the adhesive viscosity decreases and cracks appear during long-term use, the existence of connecting piece 5 can also ensure that the outer veneer panel will not fall off, improving the building safety; in addition, since the cavity between the outer veneer panel and the outer concrete layer 2 is filled with adhesive, the wall will not have a hollow sound, improving the building quality.

[0022] The connecting piece 5 is an I-shaped steel structure, and the plug-in slot 6 is in the form of "T" shape matched with the plug-in part 502 of connecting piece 5. The T-shaped fixed part 501 of connecting piece 5 can enhance the integrity between the outer concrete layer 2, improve the carrying capacity of connecting piece 5, and the cooperation of T-shaped plug-in part 502 and plug-in slot 6 makes the connection between outer veneer 1 and outer concrete layer 2 more stable and reliable, which can effectively cope with various stresses and waterproof sealing problems.

[0023] In addition, as shown in the utility model, Figure 3 The connecting piece 5 has a relatively wide width, and according to the actual width and weight of the outer veneer 1, a plurality of groups of connecting pieces 5 can be arranged on the outer concrete layer 2 along the horizontal direction.

[0024] The elastic layer 7 is arranged between the insertion part 502 of the connecting piece 5 and the deep side of the insertion groove 6, and the thickness L1 of the elastic layer 7 is 0.5-1mm. The elastic layer 7 is made of rubber material with high elasticity, and the existence of the elastic layer 7 can effectively buffer the stress caused by temperature change, building structure deformation and other factors, so as to avoid the damage of the contact surface of the outer decorative layer 1 and the connecting piece 5 due to stress concentration.

[0025] The insertion part 502 of the connecting piece 5 and the shallow side of the insertion groove 6 are provided with a gap and form a filling layer 8, and the thickness L2 of the filling layer 8 is 0.5-1mm. The setting of the filling layer 8 is to make the insertion part 502 of the connecting piece 5 and the insertion groove 6 easy to insert, and on the other hand, the adhesive between the outer decorative panel and the outer concrete layer 2 can penetrate into the insertion groove 6, further improving the connection strength between the outer decorative layer 1 and the outer concrete layer 2.

[0026] The outer concrete layer 2 and the inner concrete layer 3 are respectively provided with an outer steel mesh frame 9 and an inner steel mesh frame 10, and an X-shaped cross-shaped inclined reinforcing bar 11 is further arranged between the outer concrete layer 2 and the inner concrete layer 3, both ends of the inclined reinforcing bar 11 penetrate the insulation layer 4 and are tied and fixed with the outer steel mesh frame 9 and the inner steel mesh frame 10, and the intersection point of the inclined reinforcing bar 11 is located in the inside of the insulation layer 4. The setting mode of the inclined reinforcing bar 11 can greatly improve the overall structural strength and stability of the sandwich insulation board, and enhance the anti-seismic performance of the wall.

[0027] The adjacent sides of the outer decorative layer 1 are provided with a positioning structure in Z-shaped splicing cooperation, which can make the adjacent outer decorative layer 1 splicing positioning, and increase the contact area between the adjacent outer decorative layer 1, so that the adjacent outer decorative layer 1 can be better fixed.
